[ The World Wide Web, abbreviated as WWW and commonly known as The Web, is a system of interlinked hypertext documents contained on the Internet. [ With a web browser, a person can view web pages that contain text, images, videos, and other multimedia and go through them by using hyperlinks. [ British engineer and computer scientist Sir Tim Berners Lee and Belgian computer scientist Robert Cailliau, proposed using "Hypertext [...] in 1990 to link and access information of various kinds as a web of nodes in which the user can browse at will". [ It was released that December. [ The WWW was developed to be a pool of human knowledge which would allow other people to put their information and ideas on the web to share with everyone.
URL [ Uniform Resource Locator (URL) is a subset of the Uniform Resource Identifier (URI) that says where an identified resource is available and the program, way for retrieving it. [ The Uniform Resource Locator was created in 1994 by Tim Berners-Lee as part of the URI. [ Berners-Lee regrets using the dots to separate the route to the server in the URI, and wishes he had used slashes for the whole thing. For example,http://www.bmisitgs.com/path/to/file.html would look like http:com/serverroute/www/path/to/file.html , if he used slashes. A Berners-Lee has also admitted that the two forward slashes trailing the scheme were unnecessary [ Every URL consists of the following: the scheme name (the protocol), followed by a colon, then depending on the scheme a host name an (alternatively IP address,), a port number, the path of the resource to be fetched or the program to be run, then, for programs like Common Gateway Interface (CGI) scripts, a query string, and with HTML documents, an anchor (optional) for where the page should start to be displayed.
Internet
[ The Internet is a global system of interconnected computer networks. [ It uses the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. [ It is a network of networks that is made of millions of private and public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and optical networking technologies. [ The internet consists of millions of information recourses and services most notably interlinked hypertext documents of the World Wide Web and the infrastructure to support electronic mail. [ The origins of the Internet reach back to the 1960s when the United States funded research projects of its military agencies to build robust, fault-tolerant and distributed computer networks. This research and a period of civilian funding of a new U.S.
Intranet
[ An intranet is a private computer network that uses Internet Protocol systems to securely share any part of an organization's information or operational systems within that organization. [ The term internet refers to a computer network within a certain organization. [ The term sometimes refers to the organizations internal website but may be a main part of the organizations computer technology interface. [ The Intranet is built the same way the internet is built through client server computing and the internet protocol suite. [ An intranet can be understood as a private analog of the Internet, or as a private extension of the Internet confined to an organization [ The first intranet websites and home pages began to appear in 1990 – 1991 [ Intranets are also contrasted with extranets. [ Intranets may provide a gateway to the Internet by means of a network gateway with a firewall, shielding the intranet from unauthorized external access.
Extranet
[ An extranet is a private network that uses Internet protocols, network connectivity. [ Extranet can be viewed as part of a company's intranet that is extended to users outside the company, usually via the Internet. [ In contrast, business-to-consumer models involve known servers of one or more companies, communicating with previously unknown consumer users. [ An extranet can be understood as an intranet mapped onto the public Internet or some other transmission system not accessible to the general public, but managed by more than one company's administrator(s). [ For example, military networks of different security levels may map onto a common military radio transmission system that never connects to the Internet. [ Any private network mapped onto a public one is a virtual private network (VPN), often using special security protocols. [ Similarly, for smaller, geographically united organizations, "extranet" is a useful term to describe selective access to intranet systems granted to suppliers, customers, or other companies.
